Oil and Natural Gas Corporation (ONGC) has notified two more discoveries off the Gujarat coast, taking the number of its oil and gas discoveries in the 2010-11 financial year to 24.
The first of the two discoveries was made in block CB-ONN-2004/2 in Gujarat. ONGC has a 50 per cent interest in the block it had won along with Gujarat State Petroleum Corp (40 per cent) and Sunterra (10 per cent) in the government's seventh round of NELP bidding.
Testing at a depth of 1347.5-1315.5 metres in the exploratory well Vadtal-3 in the Chhatral formation, produced oil at a rate of 22.5 cubic metres per day and gas at a rate of 3,758 cubic metres per day (through 6 mm bean).
ONGC said the oil was found to be of very good quality, with a gravity of 41.10 API.
ONGC has since started exploration of similar fault closures towards north and into another NELP block CB-ONN-2001/1, where it has already made a discovery in May'09.
ONGC also, on 5 April 2011, notified the discovery of oil at the development well 461 in Linch Extn-I PML on the North Kadi field in the western onshore basin.
